Technical Field
The invention belongs to the technical field of water conservancy, hydropower and electric power engineering application, and particularly relates to a method and a structure for anchoring a switch station wire and a ground wire outlet anchor point.
Background
At present, the outlet of a hydropower station generally adopts a direct leading-out scheme, namely, a lead is directly led to a terminal tower from an outlet gantry, and when the outlet tension and the deflection angle exceed the limits, a mode of increasing a middle rotating tower is generally adopted, so that the span between outlet towers is reduced, the outlet tension is reduced, and the deflection angle is adjusted. The existing outgoing line mode outgoing line towers are high in manufacturing cost, the transfer tower has certain requirements on terrain conditions, and for example, the transfer tower cannot be added between river-crossing towers.

The invention aims to solve the technical problem of providing an anchor point anchoring method for outlet wires of a hydropower station, which can fully utilize favorable terrain, natural slopes or building walls and the like on site, greatly simplify the outlet wire mode without adding a middle rotating tower by matching with the anchor point anchoring method, save the engineering investment, accelerate the construction progress and facilitate and flexible construction; on the other hand, the limiting factors of the outgoing line tension and the deflection angle are small, the application range is wide, and the method can be widely popularized.
The technical scheme of the invention is as follows:
a hydropower station outlet anchor point anchoring method comprises the following steps:
firstly, constructing anchor rods on natural slopes, artificial slopes or building walls, and meeting the strength requirement after grouting the anchor rods;
secondly, after the anchor backing plate and the on-site anchor rod are provided with the holes, the anchor backing plate and the anchor rod are connected;
thirdly, connecting the anchor backing plate with a wire hanging point rod;
fourthly, connecting a wire hanging point rod with a wire clamp to lead out wires;
and fifthly, after adjusting the wire outlet fasteners and the connecting pieces (the wire outlet fasteners and the connecting pieces can be selected according to the parameters of the wires) to meet the requirements, pouring concrete outer anchor piers to protect the connecting ends of the anchor backing plate, the anchor rods and the wire hanging point rods.
The anchor backing plate is provided with an anchor bolt hole, and the anchor rod is connected with the anchor backing plate through the anchor bolt hole and a nut.
And a wire hanging point bolt hole is formed in the anchor backing plate, and a wire hanging point rod is connected with the anchor backing plate through the wire hanging point bolt hole and a nut.
A hydropower station outlet anchoring structure comprises an anchor rod, wherein the rear end of the anchor rod is connected with an anchor backing plate, and the anchor backing plate is connected with a wire hanging point rod; the connecting point of the anchor rod and the anchor backing plate and the connecting point of the anchor backing plate and the wire hanging point rod are arranged in the cast-in-place concrete outer anchor pier.
The anchor rod is anchored on a natural side slope, an artificial side slope or a building wall body.
The invention sets anchor rod in the slope as anchor body, the end of anchor rod is connected with anchor backing plate by nut. The anchor backing plate is connected with an exposed wire hanging point rod serving as a wire hanging point by a nut, so that outlet tension is transmitted to the anchor rod in the side slope through the wire hanging point rod and the anchor backing plate, and the anchor rod is anchored. The specifications of the anchor rod can be calculated and selected according to the wire outlet tension, and the deflection angle of the anchor rod can be adjusted according to the wire outlet requirement.
Compared with the prior art, the invention has the following advantages:
(1) Compared with the steel structure outlet, the anchor rod outlet is convenient to construct, few in restricted factors and beneficial to implementation.
(2) The anchor rod, the anchor backing plate and the outgoing line hanging point rod are connected through nuts in the whole process, welding and other high-altitude operation work is avoided, and the construction method is simple.
(3) The anchor rod is connected with the method through the nut conveniently and quickly, and later-period maintenance is facilitated.
(4) The anchor rod construction is suitable for various terrains such as steep terrain, canyon terrain and the like, and is beneficial to popularization.
The outgoing line anchor point anchoring method has the advantages of strong applicability, simple construction, low later operation and maintenance cost and popularization value.
Drawings
Fig. 1 is a schematic view of the anchoring of an outlet anchor rod;
FIG. 2 is a schematic diagram of an outlet anchor connection;
in the figure: 1-anchor rod, 2-anchor backing plate, 3-wire hanging point rod, 4-anchor rod bolt hole, 5-wire hanging point bolt hole, 6-concrete outer anchor pier, 7-natural side slope, artificial side slope or building wall.
Detailed Description
The following describes the implementation of the present invention with reference to the attached drawings.
The arrangement of the present invention is further described below with reference to the accompanying drawings. As shown in figure 1, the structure meanings are as follows, 1-anchor rod, 2-anchor backing plate, 3-wire hanging point rod, 4-anchor rod bolt hole, 5-wire hanging point bolt hole, 6-concrete outer anchor pier, 7-natural side slope, artificial side slope or building wall.
Firstly, constructing an anchor rod 1 on a side slope or a building wall 7, and grouting the anchor rod 1 to meet the strength requirement;
secondly, after the anchor backing plates 2 are matched with the field anchor rods 1, as shown in fig. 2, one anchor backing plate 2 is connected with 4 anchor rods 1, the connection points of the anchor rods 1 and the anchor backing plates 2 are positioned at 4 corners of the anchor backing plates 2, and the anchor backing plates 2 are connected with the anchor rods 1 through nuts;
thirdly, connecting the anchor backing plate 2 with the wire hanging point rod 3 by using a nut, wherein a wire hanging point bolt hole 5 is positioned in the middle of the anchor backing plate 2 as shown in fig. 2;
fourthly, the wire hanging point rod 3 is connected with a wire clamp to be led out;
